A new anime adaptation is winging its way to us in 2021 with the World’s End Harem manga getting the nod. The manga comes from Kotaro Shono and has eleven volumes out so far in Japan. The property began serialization in May 2016 through the Shonen Jump+ site and app. The manga, and its spinoff series, are both being released in English through Seven Seas Entertainment under its Ghost Ship imprint.
Plot Concept: The Man-Killer Virus: a lethal disease that has eradicated 99.9% of the world’s male population. Mizuhara Reito has been in cryogenic sleep for the past five years, leaving behind Tachibana Erisa, the girl of his dreams. When Reito awakens from the deep freeze, he emerges into a sex-crazed new world where he himself is the planet’s most precious resource. Reito and four other male studs are given lives of luxury and one simple mission: repopulate the world by impregnating as many women as possible! All Reito wants, however, is to find his beloved Erisa who went missing three years ago. Can Reito resist temptation and find his one true love?
